PEN'.

SPECIFICATION forming part of Letters Fatent No. 318,679, dated May 26. 1885.

Application filed December 1, 1884. (No model.)

To all whom t may con/057%:

Be it known that I, J. SPRAGUE BARD, of the city and county of New York, in the State ot' New York, have invented a new and useful Improvement in Pens, of which the following is a specification, reference being had to the accompanying drawings, forming part of this specification.

The objects of this invention are to combine in a desirable degree in a pen the qualities of stiffness and elasticity, and to cause the elasticity to be continued from the point farther back than is usual, and thereby to ob tain a pen which while having the best qualities for ordinary writing will be good for flourishing.

The invention consists in a pen the nibs of which have the forni of two diverging planes, which are united with the arch ofthe body of the pen by externally-concave curvatures or external indentures, as hereinafter described.

Figure l is a back view of a pen constructed according to my invention. Fig. 2 is a side view of the same. Fig. 3 is a longitudinal sectional view taken in the line x :r of Fig. l. Fig. 4 is a transverse sectional view taken in the line y y ot' Fig. l. Fig. 5 is a transverse section in the line a z of Fig. l.

Similar letters of reference indicate corresponding parts in the several iigures.

The body of the pen may be ofthe ordinary form, as represented, or of any other form in which that part ot' the pen which iits the holder is or can be made; but the part a a, behind the nibs, will always be arched. The nibs b b are flat, and present the i'orin of two divergent inclined planes meeting in an angular longitudinal ridge at the central slit7 c, as shown in Fig. 5. These divergent planes, in

which the ribs are formed,are continued rear- Ward of the slit, as shown in Fig. 4, and also in Fig. Lwhere the slit is indicated by a heavy The said planes are represented black line.

as continued farther back than the shoulders d d of the pen, and they are united with the arch a a ofthe body by two indentures or curvatnres, e e, which are concave externally, as shown in the longitudinal section, Fig. 3.

The indentures or curvatures e e uniting the fiat nibs with the arch of the body constitute the most conspicuous feature of my invention,

and it is by them that the elasticity of the pen is continued so far back from the point of the pen. i

I do not claim a pen with dat nibs presenting the forni of divergent planes meeting in an angular longitudinal ridge in the slit of the pen when these planes merge directly into the arch of the body of the pen, as such a pen is illustrated in the expired Letters Patent No. 10, 34S, granted to Edmund H, Bard and Henry H. NVilson, December 20, 1853; but,

W'hat I claim as my invention, and desire to secure by Letters Patent, is-

l. A pen having flat nibs in two divergent planes, which are united with the arch of the body by two indentures or externally-concave curvatures, substantially as shown and described.

2. A pen having its nibs in two divergent planes, which are continued back of the slit, and between which and the arch of the body are two indentures or externally-concave curvatures, c e, substantially as shown and described.

3. A pen having its nibs in two divergent planes, which are united with the arch of the body by two indentures or externally-concave curvatures, e e, in rear of the shoulders (Z d of the pen, substantially as herein shown and described.
